Reasoning:

While the Samsung Galaxy Note20 Ultra 5G has a fantastic display and camera system, the Xiaomi 12X better suits my priorities. I value a phone that is comfortable to hold and easy to carry around. The faster performance of the Snapdragon 870 is also a significant advantage for my daily usage, which involves multitasking and occasional gaming. The significantly faster charging is a massive convenience.
